NFS4 fstab mounting

Hello,
Is there a way to have nfs4 shares mount at boot, but also have a timout? At the moment I have nfs4 shares mounting in fstab and that works fine except if there is a network problem or if the nfs server is down. Is there a setting to have the nfs mount timout if unsuccesful so the client at least gets to a place to make changes if needed? I have tried "retry=1" and "bg" as options. I have also tried putting the mount in rc.local hoping that would allow a faster failure, but it didn't. So far, if the network or the nfs server is down, the client will not boot. Is autofs a solution?
I am mounting the equivalent of "my documents" to home, and pacman "sync" and "pkg" directories.

192.168.1.202:/pkg /var/cache/pacman/pkg nfs4 async 0 0
192.168.1.202:/sync /var/lib/pacman/sync nfs4 async 0 0
192.168.1.202:/bryan /home/bryan/Data nfs4 async 0 0

.:B:.

I use netfs, and that works just fine - boot is not halted (maybe a bit delayed, never checked) if the NFS server is broken. NFS v4 as well.

Re: NFS4 fstab mounting

Maybe my rc.conf is wrong?
MODULES=(nfs vboxdrv vboxnetflt)
DAEMONS=(syslog-ng network ntpd netfs rpcbind nfs-common @crond @alsa @cupsd dbus)

Should netfs come after rpcbind? Should rpcbind and nfs-common be there at all?

For me, if I pull the network cable from the client, boot freezes.

Re: NFS4 fstab mounting

I don't have have nfs in MODULES.
DAEMONS=(... rpcbind nfs-common netfs ...)

I mount both a NFS3 and NFS4 share in fstab. When the server/network is down I do get a delay while booting/logging in, but it still boots.

It makes little sense to put netfs before the NFS services, I'm afraid

Re: NFS4 fstab mounting

Thank you both.
I have removed nfs from the modules. I moved netfs after the nfs services. I can boot now with only a delay.  I guess I should have been referencing the NFS wiki as well as NFS4. I am not familiar enough with each daemon to recognize the order requirement (especially netfs as I can't find much documentation on what all it does)

The delay is three minutes per share. Again I tried retry=1, but it has no effect. I read on another post, that they also did not have success with retry=n. For me I get three minutes instead of the "default" two.
